11. The system according to claim 10 , wherein said processor means comprises voice recognition means for recognizing the spoken request data and outputting data including a recognition result as audio data.

12. The system according to claim 10 , wherein said processor means is located within one of said plurality of intercom units.

13. The system according to claim 10 , further including a computer comprising said processor means.

14. The system according to claim 10 , wherein said communication link is a USB wire connection.

15. The system according to claim 10 , wherein said communication link is a wireless communication system.

16. The system according to claim 10 , further including an audio interface means.

17. The system according to claim 10 , wherein said plurality of intercom units include an audio output means.

18. The system according to claim 17 , wherein said audio data is broadcast by said audio output means upon being received by substantially each of said plurality of intercom units.

19. The system according to claim 10 , wherein said audio data contains the name of a person being paged.

20. The system according to claim 18 or 19 , wherein upon broadcasting said audio data substantially each of said plurality of intercom units listen for said spoken reply data.

21. The system according to claim 10 , wherein said processor means selects one of said plurality of intercom units with the audio signal of greatest magnitude.

22. The system according to claim 10 , wherein said private audio communication channel is closed by said processor means upon receiving a signal from either of said selected at least one other of said plurality of intercom units or said first intercom unit which initially received said spoken request data.

23. The system according to claim 10 , wherein a video link is automatically established between said first intercom unit and said at least one other of said plurality of intercom units.

24. The system according to claim 11 , wherein said voice recognition means includes a memory storing a voice recognition program.

25. The system according to claim 10 , wherein said plurality of intercom units are hands free-type intercom units.

26. The system according to claim 10 , wherein said selected at least one other of said plurality of intercom units transmits an audio signal of greatest magnitude upon said spoken reply data being input.

27. A computer readable medium, having a program recorded thereon, where the program is configured to make a computer execute a procedure to establish a private audio communication channel on an intercom system having a plurality of intercom units, said program comprising: code for activating said intercom system by spoken request data input via a first one of said intercom units; code for transmitting audio data to substantially each of said plurality of intercom units in response to said spoken request data; and code for establishing a private audio communication channel between said first intercom unit and at least one other of said plurality of intercom units in response to spoken reply data input via any one of said plurality of intercom units, wherein said at least one other of said plurality of intercom units is selected for said private audio communication channel on the basis of a magnitude comparison of audio signals transmitted by said plurality of intercom units upon said spoken reply data being input.

28. The computer readable medium according to claim 27 , wherein said spoken request includes the name of a person being called.

29. The computer readable medium according to claim 27 , wherein upon broadcasting said audio data substantially each of said plurality of intercom units listens for said spoken reply data.

30. The computer readable medium according to claim 27 , wherein said private audio communication channel is closed upon receiving a signal from either of said selected at least one other of said plurality of intercom units or said first intercom unit which initially received said spoken request data.
